This example demonstrates the minimal setup required to display a text message using the D3.js library within the VizHub environment. The page shows the text "Hello VizHub!" centered on a dark blue background with large, light-colored Ubuntu font. The code imports the `select` function from D3 and uses it to target a `div` element with the ID `message`, setting its text content. The message itself is defined in a separate ES6 module and imported as a local dependency.
